Please Is there a way to clear a particular cookie with JavaScript and it is compatible with all browsers? I am using .NET to register the script during pre_load.

I believe this should suffice:

<script type="text/javascript"> function delete_cookie( name ) { document.cookie = name + '=; expires=Thu, 01 Jan 1970 00:00:01 GMT;'; } </script>

  • Will this be able to clear a cookie that has been set by a different site. ie. Salesforce. – user3214892 Apr 08 '14 at 11:42
  • For security reasons, you cannot delete the cookie of a specific domain if you aren't on that domain. This answer explains it in detail http://stackoverflow.com/a/17777005/1303004 – Basit Apr 08 '14 at 13:11
